LAMP:

Application filed July 15, 1920. Serial No. 396,398.

T0 all whom it may concern: 7

Be it known that I,'AUGIE L; l-Linsnn, a citizen of the United States, and a resident of Evanston, in the county of :Cookand State. of Illinois, have invented certain new and useful Improvements in Lamps, of which the following is a specification.

This invention relates to lamps, such for instance as acetylene lamps used by miners,

10 and particularly to certain features of construction thereof.

It is an object of the invention to provide a lamp of the character described, wherein the parts are so constructed and 10 connected as to provide superior simplicity and economy in manufacture and operation.

Other objects and advantages of the invention will appear as the description to follow proceeds.

In the drawings:

Fig. l is an elevation of a lamp constructed according to my invention, and

Fig. 2 is a plan view thereof, and

Fig. 3 is an assembly view showing the units comprising the lamp body and its external attachments, separated.

The lamp shown in the drawings is in general the type familiar in the art as a miners acetylene lamp comprising a water 80 chamber 1, to which is 'removably attached a carbide chamber 2.

These lamps have heretofore also been provided with a number of external parts such as a reflector 3, a hook l, and a pair of fingers 5, the latter elements serving to hold the lamp on the miners cap, a filling port, usually closed by a hinged cap, the equivalent for which is shown in the drawings at 6. I In the prior art, these external parts 40 have been individually soldered or otherwise secured to the substantially cylindrical body of the water chamber 1. This method of construction makes the manufacturing operation complicated and particularly complicates the burnishing operation, which is the last step in the manufacture of the lamp; when the lamp has thereon a variety of projections, such as the reflector, the cap, the hooks and the like, hand burnishing is required, which increases the expense of the manufacture.

According to my invention, in the preferred form herein disclosed, I provide a construction wherein all the external parts are removably attached tothe cylindrical body 1 so that the lamp may quickly be stripped, quickly assembled and the burnlshing and other manufacturing operations simplified. d

Thusjl'provide a U-shaped clamp 7 which surrounds the central part of the cylindrical water chamber 1, and is attached thereto by a pair of screws 8. This clamp carries all the attachments referred to. At its front end each branch of the clamp 7 is forked to provide fingers 9 which engage the rim of the reflector. The reflector is additionally secured by the burner tip 10 which is screwed into the lamp body through a central aperture in the reflector. Thus the reflector is removably attached to the lamp and may be quickly replaced, a desirable feature inasmuch as this part suffers the most breakage in use of the lamp.

At the rear of the U-shaped clamp 7 are the fingers 5, formed in this instance integrally with the lamp; the hook l, in this instance riveted to the clamp; and an in tegrally formed upward extension 11, which is forked and curled at its upper end to provide a bearing for a hinge pin 12 by which an arm 13 which carries the cap 6, is hinged on the lamp.

By the construction described the lampbody comprises a plain substantially cylindrical structure, easily treated in manufacturing operations by automatic machines. The various external parts may be applied thereto merely by inserting the two screws 8, and the lamp may as quickly be stripped.

'Furthermore repair and replacement do not require soldering operations or the like, but may be quickly performed. Thus if any of the external parts of a lamp, as shown, should be broken, a new clamp 7 with its associated parts may be instantly substituted, without withdrawing the lamp from service, and the old parts can be repaired at leisure.

j Having described my invention, I claim:

.1. A lamp of the character described, comprising a cylindrio lamp body, a reflector adapted to be detachably mounted thereon, a U-shaped band secured around said body and having arms adapted to grip the periphery of said reflector, and a hinged cap supported upon said band and adapted to close a filling opening in said body.

2. A lamp of the character described, comprising a cylindric lamp body provided With a burner and a filling opening in the top thereof, a centrally apertured reflector adapted to be applied against said body to surround said burner, a metal band partially surrounding said body and provided with projecting arms adapted to grip the edge of said reflector therebetween, and a cap for said filling opening supported on said band i 3. A-larnp of the character described, comprising a cylindric lamp body provided With a burner, a reflector therefor. filling opening, a metallic band surrounding said body and provided at its ends with fingers for gripping the edge of said reflector, and

a cap for said filling opening having hinged connection with said band.

4. A lamp of the character described, comprising a cylindric lamp body provided With a filling opening in the top Wall there of, a cap for said opening, a reflector, a U-,.
